Storms will erupt from parts of southern West Virginia to northern Alabama and will push eastward as Tuesday progresses. During Tuesday evening, the storms are likely to stretch from southeastern Virginia to southeastern Georgia.

The storms could affect the major metro areas of Charleston, West Virginia; London, Kentucky; Knoxville and Chattanooga, Tennessee; Richmond, Virginia; Raleigh and Charlotte, North Carolina; Columbia and Charleston, South Carolina; Atlanta and Savannah, Georgia; and Huntsville, Alabama.

According to AccuWeather Storm Warning Meteorologist Alex Avalos, the storms will bring the risk of damaging 70-mph wind gusts, hail, frequent lighting strikes and torrential rainfall. Some neighborhoods and rural areas could be hit with downed trees, power outages and flash flooding from the storms.

"An isolated tornado could also occur, especially in eastern North Carolina and South Carolina during Tuesday afternoon and evening," Avalos said.

In part of the Northeast, there will be showers and thunderstorms on Tuesday and Tuesday night, according to AccuWeather Senior Meteorologist Dave Dombek.

"While the majority of these storms will not be severe, a few communities could be hit with flooding downpours and strong gusty winds from the upper mid-Atlantic to upstate New York," Dombek said.

By Wednesday, a mosaic of showers and thunderstorms will continue in the Eastern states and will tend to be spread throughout the Atlantic Seaboard, including New England.

The storms will tend to be more of a nuisance with the possibility of travel delays and disruptions to outdoor activities on Wednesday.

"While widespread severe weather is not expected, a few locations could be hit with a torrential downpour and brief wind gusts, especially along the Atlantic Seaboard," Dombek said.

Some drier air will tone down the shower and thunderstorm activity over the Appalachians.
